Fixing the Auto-Generated Helm Chart

Even though the code of the application is small, I will save you from going through it. Instead, I’ll let you know right away what’s missing and what parts of the chart need to be added or modified.

Adding DB environment variable

First of all, the application requires an environment variable called DB. The code is using it to obtain the address of the database. That brings us to the first thing missing in the chart generated by Jenkins X; there is no definition for MongoDB.

The first step is to open charts/go-demo-6/templates/deployment.yaml in your favorite editor. That’s where the Deployment for the application is defined, and that’s where we need to add the variable.

Please locate the code that follows.
